Hello, everyone! One and all! I'm dad90, and for the first time, I'm adopting a story from a user named arcana1375 who wrote The Undead Dragon Emperor. Apparently, he deleted the story, but thanks to the original idea user named 2015 Lewamus Prime, I've the first chapter under control, but of course, there's going to be some differences and plot twists along the way.

Also, at the same time, I've been challenged by Glorious Burden, another good friend of mine, and this is what he came up with:

Highschool DxD crossover challenge:

Crosses over with: Omamori Himari, Trinity 7, Heaven's Lost Property, Date A Live

Characters and Elements will also be included from: Arcana Heart (Game series), Brandish (H-manga), The Testament of Sister New Devil

Genres: Action, Adventure, Comedy, Romance, Mecha, Drama, Fantasy, Sci-Fi, Supernatural, School Life

Warnings: Violence, Strong Language, Sexual Content

Universe: Merged Universe

Using: Animeverse/Mangaverse

Now, I'm currently watching Date A Live's first few episodes, and try to find out why that series is popular.

Also, I don't own anything except for my own OCs, and Zack Orion belongs to 2015 Lewamus Prime.

And as I do, get ready for…

Season 1 START!

Opening Act: The Undead Dragon Emperor & The Arrival of the 2 Stepsisters


(3rd-Person POV)

March 10th, 1993.

The day the whole world stood still.

An event that has come to only be called "The Catastrophe" hit Earth. The Catastrophe lasted 18 hours, during which time, over 3 billion people simply dropped dead with no immediate explanation. Curiously, though the vast majority of that number died in their sleep, of those that didn't, only a scant few died in circumstances that would put other people's lives at risk.

Try as the people of Earth might, they were unable to pin down any sort of ultimate, clear reason WHY the Catastrophe occurred, or why it hit who it hit. All they could figure out was that the vast majority of the cause-of-deaths were due to spontaneous heart attacks that proved lethal to those they hit. Attempting to pin down who the Catastrophe targeted proved useless as well; though it seemed to hit third-world nations quite hard to the point where some of the smaller ones simply no longer exist, that it seemed to largely miss the young and very young, and the lower class seemed to be hit somewhat harder than the upper classes, the fact is that the 3 billion dead included vast numbers of people from all walks of life, from every nation, of every economic class. The completely inexplicable nature of the Catastrophe only baffled scientists and doctors further, as autopsies revealed that the deaths were not caused due to chemical or biological weaponry, nor were they caused by ANY sort of obvious attack or foul play- only that 3 billion people, many of them perfectly healthy immediately before their deaths, just suddenly died.

Of course, they wouldn't know that because….

** At the Dimensional Gap **

….the main reason for all of these deaths?

The Second Great War.

This one involved with the 3 Factions: Angels, Fallen Angels, & Devils. But that's not all. It was also involved with many other supernatural races, including Ayakashi, Vampires, Kitsunes, just to name a few. But the top 3 involved in this war are Dragons, Angeloids, and Spirits.

The Angeloids (a portmanteau of Angel and Android) are a series of hybrid machines made by Daedalus and Minos. They were created to obey the orders given to them by the masters of Synapse, the lost portion of Heaven, in which Michael, the leader of the Angels, watches over.

The actual process is unknown but Angeloids are given life from biological engineering since they have organs, fluids, etc. What is known is that, despite their fragile appearance and human characteristics, they are endowed with great strength, speed, and knowledge of battle as well as being extremely difficult to harm by human measures.

Angeloids are made in several different types as powerful warriors, medical technicians, and strategists, each of which is specially made for a certain task that is primarily (but not uniquely) combat-related.

They come either in First Generation, (in which both Daedalus and Minos created, in which they were determined by a mixture of their battle abilities, computational processing capacity, and emotional control), Second Generation (only created by Minos in an attempt to destroy ALL 3 Factions for his own pleasure), or an Unknown Generation.

Then, came the Spirits, as they have proved to be one of the BIG forces to be reckoned with. They are extraordinary beings from a different dimension. Through their own will or not, it is unknown, but each time they come through to this world, they create a spacequake that is similar to a bomb explosion which destroys everything that it engulfs. Each individual Spirit is unique in personality, power, and their knowledge of the world.

Each individual Spirit has their own unique powers and abilities as well as the amount of "Mana" they hold within their bodies. However, all Spirits have the same ability of creating their own Astral Dress, as well having an Angel (Not to confuse with the ones from the 3 Factions), plus the ability to fly.

And last, but certainly not least, the Dragons. They are known to be one of the most powerful and prominent creatures of all time. Dragons are beings created from large masses of energy who act freely and selfishly. Despite this, Dragons have an extremely high level of intelligence.

Dragons are creatures that represent power. As such, in all ages, Dragons are admired, respected, and feared by all. The Dragons are the only creatures whom, as a race, did not side with any of the three factions in the 2 Great Wars, unlike the Youkai, European Monsters, spirits, fairies, and other supernatural races. That also includes Angeloids and Spirits as well. However, some individual Dragons "did" (Keyword: DID) join one of the Three Factions.

It is also a known fact that it is a grave mistake to anger a dragon of ANY level, whether it be a Low-class Dragon or one of the Heavenly Dragons.

And the most prime example of this was when the Spirits had the NERVE to fight against the 2 strongest Dragons ever: The Great Red, the Apocalypse Dragon and True Red Dragon God Emperor, and Ophis, the Infinite Dragon God. And with the Spirits and these 2 Dragons fighting alone, THAT was the major cause of the 3 billion deaths in the Human World, despite the fact that they were all fighting in the Dimensional Gap.

And when all was said and done, not only humans, but many races of the Supernatural suffered severe deaths, including the loss of the 4 Great Satans and 40 out of the 72 Pillars for the Devils, more than ¾ of their armies lost for the Fallen Angels, and Heaven split in 2 for the Angels.

** Somewhere in Synapse **

Daedalus could only cry as she saw the Human world in great turmoil.

She is a calm and caring angel she cares for all her daughters and the rest of synapse. She is highly intelligent is synapse's top scientist, she hates cruel and manipulative people like Minos, who is still an Angel, somehow. It's a wonder that he hasn't fallen yet after all of the damage that he has done. Not to mention that HE was the one that started the 2nd Great War as an excuse after seeing the Spirits fight against the Dragons. She has long blue hair and has white wings and wears a long white necklace. Unlike other Angels, she's always bare foot. For some reason, due to her weak health, she always sit on a cloud-like machine that Michael created for her.

Daedalus is also one of the few that learned that God had died during the first Great War, and she felt devastated as she was his godfather. Now, as the Angels currently checks on her from time to time, she's hoping that one day, all of this war will come to a halt once and for all in the hopes of restoring humanity in the Human world.

Well, little does she and many other Supernatural races know is that these 2 boys-turned-Dragons, Dayo "Mugen" Kayode, the Son of Infinity, and the son of Ophis, and Zack Orion, the Undead Dragon Emperor, and the only one lucky enough to survive the blood of Samael, the Dragon Eater, would be the ones that changes the fate of the entire world and the Supernatural worldwide.

Not to mention that she has inverted nipples. Because of that, she has been given the title of The Supreme Goddess of Oppai.

[Morning, brother~~!] the 3 sisters sang, hugging me from all over the bed.

"M-Morning…" I replied to them with a blush on my face, knowing that the girls are a bit too close to me, but they didn't care as they just giggled.

But then….

BAM!

"Uuggh…"

"That must be Kotori waking him up again…" I sighed annoyingly. "I just hope Zack's stomach is okay after that…"

Who are Kotori and Zack, you ask? Well….

** Next door **

(3rd-Person POV)

One person in bed is about to be woken by his adoptive little sister into the most dreadful situation possible.

The person jumping up and down on his bed is a middle school girl with twintails. She has red eyes and very long, light coral-colored hair that is usually tied with ribbons in three variety of colors of both hair and is separated by each side, called a twintail hair. She also has antenna hair (アホ毛 ahoge?) that always sticks out on the top of her head.

"What's wrong, my darling brother?" Kotori asked.

"Get off of me! You're heavy!" the brother inside the bedsheets replied. He would immediately regret that.

Because Kotori jumped up high, showing her panties for a brief before planting her foot on the boy's gut…

BAM!

…hard!

"Uuggh…" the boy groaned.

But Kotori didn't care and just said, "You just said 'Uuggh..'."

The boy revealed to be a man with wild black hair that's a bit long. He has a thin body with some abs and a bit of muscle in him, and his skin is light brown. His face is angular, have Ocean or sky color eyes and he has two sets of teeth fangs like and possessed a wonderful smile of an angel or a great nice guy or a fearless or fearsome. One set looks like a normal human's, while the other is retractable and are sharp teeth even with fangs (mainly used to scare opponents). He has a long red scar on his left eye and a red shape fang under his right eye.

(Dayo's POV)

As I enter into Zack's room, I can see that he's once again been disturbed by Kotori.

"Hey! Why are you sleeping again?" Kotori asked while Zack begins to cover himself in the sheets.

"Yo, Koko!" I said to her. Yes, I call Kotori "Koko".

"Brother D!" Kotori said as she jumped off of the bed and hugged me. "Zack won't wake up!"

"That's because you've been pushing his patience," I warned her. "Sometimes, he has a bad temper. And since you pounced on him again, I might as well make him feel better."

I then proceeded to Zack and whispered, "You all right, man?"

"I am," Zack replied. "Just make sure she's in the family room before I tease her with my 'virus' again."

I just nodded and proceed to Kotori who's currently hugging my sisters as I said to her, "Koko, Zack will be up shortly, but I suggest that you wait in the family room now."

"Why?" Kotori asked.

"Because Zack's got the 'If you don't let me sleep for at least another 10 minutes, I will tickle my little sister uncontrollably' virus. Also known as the T-virus."

That's one of the biggest lies I've just said, but Kotori seems to buy it.

"What?!" Kotori asked in horror as she and my sisters hugged each other in fear.

"So I suggest you just run now, while he can still control himself."

"What about you, Plushy-chan?" Yant asked.

I gained a small tickmark, but quickly shook it off and said, "Don't worry. I'll take this one for the team!"

"We love you, brother! Please be safe!" my sisters shouted as they and Kotori ran to the living room.

I sighed heavily and said to Zack, "They're gone."

Zack finally woke up and said, "Good grief. Why can't I sleep in peace sometimes?"

"Well, you should be glad that we're finally with a peaceful family now, despite the fact that the parents of the Itsukas are now starting their new lives in North America, taking care of the children in an orphanage center," I replied to Zack.

Yeah, Zack's life has been mind-boggling twisted after the past 5 years, and now he's on the road to recovery from his horrifying ordeal, and what an ordeal he has been through.

(FLASHBACK TIME! – 8 years ago)

(3rd-Person POV)

The year was 2015. Around another area in Japan.

It was the first day of Middle School for Zack Orion at the age of 11, and let's just say that he's not a happy camper.

In fact, he's walking to school with his head down to hide the scar his dad gave him after a vicious fight with him last night. He didn't think today would go all that well, and he was right.

"Look at him."

"What a loser."

"Let's beat him up even more."

The scar Zack had has scared a lot of people and he got bullied constantly. However, a savior managed to aid his way.

"Leave him alone, you idiots! Don't you have class you're supposed to attend to?!"

That voice belonged to Rinko Kuzaki. She has short, golden brown hair with split bangs and matching brown eyes. Her most recognizable features are the 2 red ribbons she wears on both sides of her hair and her petite figure.

"Shoot, it's that sport addict Rinko. Let's get out of here before she beats us up."

"You got lucky that you got saved by that flatboard, loser!"

"WHO ARE YOU CALLING A FLATBOARD?!" Rinko shouted and threw some rocks at the boys, each of them hitting them in the head, forcing them to retreat.

"Th-Thank you," Zack said nervously, after seeing her protect him. "I-I'm Zack Orion."

"I'm Rinko Kuzaki. It's a pleasure to meet you!" Rinko said cheerfully. "Don't let that scar on your face wear you down. And in case you get bullied again, let me know. We're friends, right?"

Zack couldn't believe his eyes. At long last, he finally made a friend, and to him, it's a huge accomplishment.

"Yes!" Zack said cheerfully. For Zack, he felt a little safer, thanks to his new friend Rinko.

(Weeks later)

When he got to his mother's house, Zack saw his mother watching the TV, hearing a special report. When Zack saw what his mother's seeing, he couldn't believe it.

His father was dead by police shooting.

Last night, he got drunk and got stopped by police who asked him to take a sobriety test. The policeman's response was being stared in the face in the barrel of a gun that his father wielded, in which he was actually trying to kill his mother and Zack himself. However, for some reason, his gun jammed, saving the trooper's life.

And as the man began to drive off, the trooper fires some bullets at Zack's father, in which one of them hit the father in the head, knocking him out, but with his foot on the gas, the car accelerates towards a telephone pole…

BAM!

…causing a blackout to the entire neighborhood, while his head slammed hard on the glass. He has already been killed from the trooper's shot.

And now, after years of constant abusing, Zack felt a huge weight off of his shoulders. Even his mother's crying in joy as they were now finally free from the father's wrath.

(Next day)

In school, Zack felt much more confident as he held his head up high because he's no longer afraid. In fact, some of the bullies even managed to leave him alone as well. At this point, noting could scare him. And the best part? He and Rinko made a few new friends.

2 upperclassmen named Rias Gremory and Akeno Himejima, and an underclassman named Koneko Toujou.

They all treated him kindly and they were able to play together a lot. Koneko seemed to like spending time with Zack and Rinko, due to her love of cats. Either Zack or Rinko would get their lap sit by Koneko during lunch hour.

"Do you even eat regular foods at all?" Rinko asked.

"I usually… eat candy…" Koneko answered as she ate another chocolate bar.

"You do realize that eating too much candy is bad for your health and teeth, right?" Rinko asked, worried about Koneko's eating habits.

(3 years later)

Zack was a little disappointed when he saw Rias and Akeno go to High School 2 years ago, and he was even more disappointed when he saw Koneko skip a grade and proceeded to High School last year, and now, it was his turn to head to High School, but at least Rinko is heading towards the same school with him.

** At Kuoh Academy **

The school Zack and Rinko were heading to was Kuoh Academy. Originally, it was an all-girls private school, but for the first time this year, it's now co-ed. It's also here that Rias, Akeno and Koneko are attending here as well.

Unfortunately, some perverted boys attend here as well.

Kuoh Academy boys' uniforms consists of a black blazer with white accents over a white, long-sleeved button-down shirt with vertical linings, a black ribbon on the collar, matching black pants, and brown dress shoes.

Kuoh Academy girls' uniform consists of a white long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, a black shoulder cape and matching button-down corset, and a magenta skirt with white accents.

But Zack didn't see any one of the girls he wanted to see during the opening ceremony. He heard everyone talking about them, but he couldn't seem to find them. So he went about his day hanging out with Rinko, but with a little more company with them.

They were Mikako Satsukitane, Sohara Mitsuki, and Eishirou Sugata. And boy, were they….something else.

At the time, Mikako was the Student Council President at the age of 15. Mikako is a tall young woman, she has long purple hair with two ribbons tied to both of her side burns. She has squint-y dark-purple eyes and maintains a constant grin, which reflects her sadistic attitude. She is equal in height and weight to Eishirou Sugata. Mikako is an upperclassman and she is Eishirou's childhood friend, whom she refers to as "Ei-kun," and the heiress of a Yakuza family. She is manipulative, a genius intellectual, cunning, highly intelligent, surprisingly strong and sadistic, usually towards Zack, her new "target".

Eishirou is a tall young man who sports delicate white hair and blue-green eyes. He dresses in his school uniform, for those are his only clothes. He also wears large, rectangular glasses. His facial expression is almost always neutral. He is the President of The New World Discovery club, and strangely enough, for some reason, he lives in a tent near a river and is always seen wearing his school uniform, as he has no other clothes, and continually praises various European explorers (such as Magellan and Columbus). He is highly eccentric and has some past involvement with Mikako's family; her servants even call him master. He is also equal on combat abilities with Mikako.

And Sohara is a teenage girl of average height, sporting long brown hair, which is usually kept in a pony tail held by a ribbon. She has large brown eyes, and may still be growing. Her measurements are as follows: Bust: 93 cm, Waist: 59 cm and Hips: 84 cm. She stands 158 cm tall (5'2) and weighs 49 kg (108 lb). As a child, she was constantly ill and thus had few friends. Her most notable features are big breasts, her dreadful Karate-Chop of Doom, in case that any perverted boys even try to look at her body, and her HORRIBLE cooking.

Evidence?

When she cooked one of the eggs, it had a DEADLY aura all over it, and NO ONE even tried eating it.

And with these new friends, Zack told them a lot of jokes, talking and messing around, avoiding some of Mikako's sadistic moves, and stop and prank perverts for disrespecting women.

Because of these, he's well-liked as he was funny and lots of girls wanted his number, but Rinko and Sohara will have NONE of it. Even Zack politely declined since they didn't know him or showed any interest in doing so, just like Eishirou, giving him the title of "The Cold Scar Prince", making them want Zack even more.

As Zack was enjoying his days throughout the school, he finally saw them down the hall.

"It's the Two Great Ladies, Rias and Akeno!" one of the girls said, and everyone stopped to take a look.

And why not? They are the two most popular ladies of the school, Rias Gremory and Akeno Himejima.

Rias is a beautiful young woman who appears to be in her late teens with white skin, blue eyes (blue-green in the anime) and a buxom figure. Her most distinctive feature is her long beautiful crimson hair that reaches down to her thighs, with a single hair strand (known in Japan as ahoge) sticking out from the top. Her hair also has loose bangs covering her forehead and side bangs framing her face.

Akeno, Rias' best and childhood friend, is a young woman with a buxom figure around the same age as Rias with very long black hair and violet eyes. Her hair is usually tied in a long ponytail, reaching all the way down to her legs with two strands sticking out from the top and sloping backwards, with an orange ribbon keeping it in place.

And as Zack walked up to them, the 2 girls saw him and the look in their eyes said it all.

Polite Acknowledgment. It was as if they forgot all about him.

And then they left, laughing as if they hadn't seen a friend for quite some time.

'That's it?' he thought sadly. Was all the time he waited for gone to waste as they forgot about him?

'Could Koneko forget me too?' he thought to himself as he headed back to class, looking dejected.

** 2 hours later **

Rinko and Sohara were worried. They haven't seen Zack, and classes have already ended and most of the students have already gone home.

Zack was looking down at the street while being on an overhead bridge. His thoughts were clouded ever since that meeting earlier, not forgetting the look in their eyes.

'So this friendship was all but a lie…' he said to himself, as he thought that this friendship is to just take a pity on him with the scar he had. And that annoyed him to no end. He hated people like that.

But as bad as this is, it's about to get MUCH, MUCH worse!

As Zack stood fuming on the bridge, he didn't notice a girl was trying to talk to him.

"Um, excuse me?" the girl asked.

It was then that Zack was out of his thoughts and looked at the girl who tried speaking to him. And needless to say, she was very cute. Long black hair that reached past her waist, deep brown eyes, and she was wearing a light pink shirt with a black skirt.

"Is your name Zack?" she asked.

"Yes, I am," he politely answered.

"I'm glad I found you!" the girl said cheerfully. "My name is Maria Lyken, and I go to the same school as you, and…and….I was wondering…..um…"

Then she said out loud….

"Would you please go out with me?"

She then bowed her head, hoping for a yes.

No one has ever done that to Zack. Never had anyone shown so much conviction and respect, especially since he had done nothing to earn it. And maybe this was what he needed. Someone who would actually care about him. Not like Rias and Akeno. Maybe for Sohara and Rinko, but Mikako is also a big No.

He smiled and spoke, "I would be honored of going out with you."

Maria looked at Zack with an expression of pure joy as she hugged him and let him go, giving him a kiss on the cheek and wrote her number on a piece of paper before heading home. He smiled too, at least something good came out of today.

But little did Zack know is that he is walking into a trap….

(Weeks Later)

Zack was once again happy, now that he's got a girlfriend and he got over Rias and Akeno forgetting about him. Though he had yet to see Koneko, but he honestly thought that she had forgotten him as well. However, he didn't tell his friends about his girlfriend. It would be a mistake that would cost him his life….

(Next day)

"Zack? Can I come over to your house after school?" Maria asked to him after classes were over.

"Sure," Zack answered. "I do have something that I need to show you. I'll see you then."

That would be the last pleasant conversation between these two before an epic Killing Spree would begin….

(Hours later)

After classes, he led Maria to his house, so he could meet with his mother and they would all formally meet.

What happens next changes his entire life forever.

"Oh! I forgot to give you that present. I left it in my room. Excuse me," said Zack as he ran upstairs to get it. And as he ran up to his room to grab the necklace he got for Maria….

"AAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHH!"

A loud scream from his mother was heard. Zack quickly rushed downstairs and what he sees is the most devastating moment he ever saw.

(WARNING: Gore scenes!)

His mother's body was torn apart.

"Please…..run…"

Those were the last words Zack heard from his mother before her head was crushed; her brain splattering the floor, and then Zack looked at the foot of the person who did it.

It was Maria. And her outfit changed as she looked completely insane.

"W…Why….?" Zack asked in horror.

"It's because I'm a Stray Devil," Maria answered in a now more malicious tone. "I used you and I never liked or loved you in the first place. Some kid you are."

Stunned by her words as she was laughing at him, Zack couldn't move. She was another liar, just like Rias and Akeno, saying they'd always be with you, and then they leave you.

But now, what could he do? Both of his parents are now dead, and he could join them at any moment.

"Hahahaha! So you can't move, huh?" Maria asked. "Then let me help you."

Maria walked up to him and punched him in the head hard!

PUNCH!

The last thing Zack saw was multiple pairs of wings. Some like a bat, others like a crow before he knocked unconscious.

** At an Abandoned Warehouse; 8 months later **

How long has been in here?

Zack didn't know anymore. In fact, has Sohara and Rinko and his other friends been looking for him all this time. Again, he doesn't know.

Unfortunately, throughout the days, it has been an eternal nightmare as they blended together into a mass of inky darkness, never knowing where Zack was or how long he had been there.

(WARNING: Even more Gore scenes! This one isn't pretty!)

His only marker for any idea of time was what torture he had to endure from the forces of the many Stray Devils and rogue Fallen Angels. Cutting off his fingers, letting them regrow, only for them to be ripped off again. He didn't know how he regrew them, but he wished it would stop.

He was beaten up, drowned, torn apart in so many places by chainsaws, starved, and they even jammed metal rods into his ears AND eyes!

"AAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHH!"

"So, what kind of punishment shall I do to you today?"

That voice belonged to Maria, who enjoyed torturing Zack throughout these months. Always changing her tone just to mess with him. It was then that she came up to him with a syringe in her hand full of some type of black fluid.

"W-What is it?" he asked weakly.

"This is the blood of Samael, the Dragon Eater," Maria answered, widening Zack's eyes in terror.

Throughout the torturous months, Maria taught everything about the Supernatural world to Zack.

Devils, Fallen Angels, Angels, Youkai, Angeloids, everything. Including the 2 Great Wars, and the Catastrophe. The only thing she left out are the Spirits.

And one of the last things she told him was that there was a special dragon with cursed blood. That was Samael. And just a tiny bit of it was enough to kill Dragons. Even the 2 Strongest Dragons in existence, The Great Red and Ophis, were not invincible against Samael.

"Then does that mean….I have a Dragon inside me?" Zack asked in conclusion.

"That's right," Maria answered with the full syringe in her hands. "And this would be the very last thing you'll ever see. Don't worry. Your death will be as painless as possible."

Zack wanted to die at this point anyway, but not from that.

"Dear God, anything but that!" he protested. He tried to move away, to run, and do something to prevent this.

But he couldn't. He didn't have the strength to move.

"NOW DIE!" Maria yelled as she jammed the syringe into his neck, letting the curse flow into his bloodstream.

Now, to say "Painful" would be the lightest description of it.

It burned like hell, like his blood turned to fire and was flowing even faster. It was then, and only then he didn't want to die. He couldn't die until Zack wanted revenge against those who ripped him from his life, who killed his family, who tortured him to the point of insanity.

And it was her, who lied and broke him more than anything else done to him. Zack could feel his soul dim and he said…

"No; I will not die here. I will live to see the sun!"

Feeling the rush of wind as he ran, he would do everything he ever wanted to do. And it would start here.

** Outside the Warehouse **

A large, black Dragon was flying around town above 20,000 feet of them. He's Dayo 'Mugen' Kayode, the son of Ophis, the Infinite Dragon God, and his late father, Gilgamesh, the King of Heroes. He's flying as he was trying to recover from a friendly practice battle with his mother Ophis, and his uncle, The Great Red.

Why he flying around the Human World? Nobody knows but him, but little does he know is that doing this would be the best decision he would ever make, because….

"! What was that?" he asked as he felt the cursed power of Samael. "It can't be! That dragon eater… he should've been in Cocytus, all sealed up! Something's wrong here…."

He then sensed where the power is coming from and quickly flew down there and check it out.

** Inside the Warehouse **

Maria, who had been laughing up to this point, was now startled as she saw Zack begin to rise up. She was in shock and in horror as she thought Zack would be dead by now, because at that moment, she could feel Zack's soul dissolve into nothingness, yet he was still there.

His conviction and will to live had been enough for him to stay alive without a human soul.

"How are you still alive?!" Maria asked in anger as she had her mind racing, and might have figured it out until he changed.

Suddenly, the temperature in the warehouse dropped by 50 degrees instantly, covering the metal in frost as the room was already 40 degrees to begin with, but Zack seemed unaffected by this. His hair turned bright white as his eyes lost their pupils and irises turning pure black, giving off a crimson light. His skin turned a very pale blue, like his whole body was frozen. Then, black cracks began to appear in his skin, like cracks in ice. His teeth sharpened to a point like a shark. But the most terrifying part of all was his wings. They sprouted from his back like a dragon, but only these wings were made out of bone, like they wouldn't even be able to fly. Even his tail is made out of long bones, but it also has a blade in it. His breath, if he even need to breathe at this point, didn't show.

He let out a scream that sounded a rasped shout.

SCCCCCRRRRRRRRRRRRRRRRRRRRREEEEEEEEEEEEEEEEEEEEECCCCCCCCCCCCCCCCCCCCCCCCHHHHH!

It was terrifying as Maria, and now, the rest of the Stray Devils and Fallen Angels gathered around to kill him, but felt their souls being forcefully pulled out. They even saw the small colored ball that was their soul sticking out of their chests.

"W-What is this?" one of the Fallen asked in horror.

Zack wanted to make their punishments as painful as possible before killing them, one by one.

What none of the enemies knew was that the sudden influx of power alerted all the devils in the area, including Rias and her peerage. It also alerted Dayo in the process as well.

"Kill him quick before he tries anything else!" Maria shouted.

The Fallen Angels that recovered charged towards Zack with their light spears, but they were surprised when the spears passed through him harmlessly. Somehow knowing what to do, he focused and smoke came from his body, spilling onto the floor and reforming a smoke version of him.

Then the two raised their hands and the gravity around the Fallen Angels and Stray Devils increased to 10x the gravity. They all fell to the ground, struggling to get up, but to no avail. He then increased the gravity on their arms while the rest of them went into 0 gravity.

It was incredibly painful for them.

"P-Please stop! I forgive you! I really love you! Please have mercy on me!" Maria cried, who was now in tears.

Zack drifted over to Maria and laughed and said, "I hate liars and people who killed innocent people."

"And so do I." (No, I'm not making a Rick-Roll impression)

That voice belonged to Dayo, who has seen the whole thing.

"Y-You are…" Maria said with even more worry in her voice.

"That's right. Your worst nightmare," Dayo answered before many black holes formed around the Stray Devils and the Fallen Angels, forcing them to fall inside the holes at 100x the gravity where they got speared by many spikes in the bottomless pit, killing them instantly. (Just imagine them falling to the spike pit like the Mortal Kombat series from the Nintendo 64 series)

From there, Zack returned to normal and asked, "W-Who are you?"

"I'm Dayo Kayode, a Dragon," the black man said in his human form. "And I've felt the power of Samael going inside you, and I'm wondering how you managed to survive."

Zack then said, "Let's get out of here and I'll tell you everything."

Both Dayo and Zack manage to get out of the warehouse, and just in time before Rias and her peerage managed to find themselves where the 2 boys were. The Abandoned Warehouse was now nothing but an Abandoned Warehouse, but they shivered from the cold air. Somehow, they've finally felt the one thing missing.

Their friend Zack Orion. Though they didn't know why, they've felt sadder than they'd ever felt, as if they forgot a childhood friend. And somewhere deep down inside, Sohara, Rinko, Mikako, and Eishirou felt it, too.

** At Zack's house; 2 hours later **

The entire house was destroyed and Dayo made a grave for Zack's mom after Zack told him everything about what had happened.

"Being suffered indeed! Don't you worry!" said Dayo. "That will no longer happen as long as I'm around. Zack, now that you a Dragon and without a soul, I think it's high-time that you should get ready for a new season. This new season will be NOTHING like this ever again. From this day forward, I, Dayo 'Mugen' Kayode, will not only be your best friend, but we're also going to become brothers."

"Brothers?" Zack asked.

"Yes. Brothers-for-life! And this time, it's an absolute promise. A promise that I will NOT back down. You won't be forgotten or suffer from all of these things ever again!"

Dayo held his hand out to Zack, and instead of shaking it, Zack went to Dayo and hugged him and started crying, even though he doesn't have a soul inside anymore.

It was from there that Dayo and Zack are now brothers/best friends for life and Zack had officially become the Undead Dragon Emperor.

(END FLASHBACK!)

(Dayo's POV)

** At the Living Room **

After telling Kotori and my 3 sisters that Zack is back to normal, we were all getting ready to go to the diner not only for breakfast, but to also meet the surrogate mother of the Chichiizumi family, Kuhdelka Laura Austin. We call her Kuki.

And as my sisters…. "reshape" their figures to their curvy and busty types, the TV came on with the special report that now happens often.

"Early this morning, a small spacequake occurred on the outskirts of Tenguu City. Only minor damage was done to the area, and there have been no reported casualties or wounded. Currently, there are still no explanations as to what is behind the spacequakes. Also, if you're outside at night, be on the lookout for Fallen Angels."

"Another one?" Di groaned as she put on her shoes. "It's too close for comfort."

"Yeah," Kotori agreed as she started eating a lollipop.

Ah yes. Spacequakes. Let me explain what they are.

Spacequakes are disturbances in space that destroy everything in their wake.

Of course, I know who are the causes of these disasters: Spirits.

How? Well, thanks to fight between The Great Red, my uncle, Ophis, my mother, and those Spirits 30 years ago, which was also the start and end of the 2nd Great War, billions upon billions of people were killed and laid waste to cities, towns, and villages when these spacequakes are touched down, thanks to these supernatural entities. And even now, there are numerous spacequakes all over the world happening for at least half a year, with most of them hitting Japan, in which is we're at right now.

"They've been happening a lot lately," I noted, frowning. "And it's a disappointment that those Fallen Angels actually have the BALLS to reveal themselves to human society, to make matters worse."

"True," Kotori agreed, before whispering to herself, "We might have to move up the schedule, but we'll see since Aunt Kuki is bringing 2 more girls into the mix…"

Zack and I heard that, but before we could ask what's going on….

"We're ready, Plushy-chan!" Yant said to me, hugging my right arm and into her soft, but huge bust. "Let's go!"

I could only blush and sigh, "Yeah… Let's go…"


END OF FIRST HALF: Dayo, Zack and the gang head to the restaurant

START OF SECOND HALF: A door with a note that has a broken lock with the lights turned on inside.


** At the Pooters Restaurant ** (Yes, I went there as a Hooters expy)

My eyes are currently twitching every time I go to this restaurant. Because all I see are lots of cute and sexy girls wearing white shirts and orange short-shorts that only covers their private parts, and most of all…

"Aw, come on! Aren't you glad that we got 2 new stepsisters joining our wonderful family? Even Gala is excited!"

…that voice you just heard is the Chichiizumi surrogate mother, Kuki. She happens to be the Manager of this restaurant, and my 3 sisters are working here, too.

Character Stats:

Kuldelka "Kuki" Laura Austin

Age: 31

Blood: AB

Race: Korovanoid (Half-cow, Half-Succubus)

Height: 184 cm

BWH: About 135/73/121

Specialty: Titled "The Lusty and Busty and very Dangerous MILF"; Manager of Pooters Restaurant (The female workers here have HIGH sex-drives)

Kuki has a figure that almost every sexually-frustrated mom would like to have: Medium-sized pink hair to hide her cow ears, green eyes, a cow tail (people think of this as cosplay for some reason), brown boots, a red miniskirt, and a shirt that only covers her breasts (She hates wearing bras, for some reason).

"Now having more sisters, especially surrogate sisters, is a bit too much for us at this point," I said to Kuki flatly, earning a playful bonk on my head. "Why are we taking them in again?"

"Let's just say that it's a favor cash-in from an old friend of mine, and let's leave it at that," Kuki answered as she placed a drink on another tray, in which one of the workers in return picked it up.

"Leaving it at that makes us more than a little skittish, Kuki-mom," Zack said with an annoying glare.

"Could you perhaps be a little more specific?" Kotori asked.

"No. I want you all to see them as regular people before using those enhanced powers of observation of yours. Since Pridys Chichiizumi, the Queen of the Pururina Kingdom and the true mother of the family, approved of this, she has gladly given me the opportunity for you guys to treat them as if they were family," Kuki said sternly, with me grumbling a bit before Zack, Kotori and I all nodded.

"All right," I grumbled. "But what I am worried about is if you try and teach her any….inappropriate things."

Kuki just smirked and said, "Oh, I would never do that to her, especially when I'm working here 18 hours a day."

And as Kotori continued eating her favorite breakfast here, and as my sisters try to make me look at their sexy figures, Zack and I are waiting patiently until the 2 new additions to our ever-growing family arrives.

"By the way, they should be here by now," said Kuki as she looked at the clock on her smartphone, which now has 5G technology.

"Or this is one huge prank of yours," Kotori said in a bored tone as she licks her lollipop.

Oh yeah, did I mention that sometimes Kuki-mom is one hell of a dirty trickster?

"No, it isn't! This is serious!" Kuki-mom snapped back while blushing.

"I'm going to use the bathroom. Be right back…" Zack said as he got up and left the table, while I grumbled, "Bleah. 2 new stepsisters…."

Then, I look towards where Zack is heading, but what I saw next made me REALLY nervous…

I just saw Zack opening the bathroom door for Men, not noticing the note on the door that said…

The lock is currently broken. Also, the toilet in the Women's restroom is not working. So please knock first. – Manager Kuki

Oh. Sh*t.

I quickly went to Zack to warn him, but I'm afraid it's too late as what he saw was an unexpected and surprising sight, as someone (naturally) was already in there, and forgot to close and lock the door when using it. Then again, Zack forgot to knock because of the broken lock.

"Let me guess. It's a girl, isn't it?" I asked with a deadpanned tone.

Zack could only nod silently as he saw an incredibly young woman of average height, with crimson hair that reached down to her waist, violet eyes, fair skin, a distinctly voluptuous body with G-cup breasts, and wearing a casual outfit that consist of a purple blouse under a white apron skirt.

Oh, and she was just pulling up her panties when she stopped midair and stared at Zack in shock.

Zack was in shock himself as this girl reminded him of someone important.

Rias Gremory.

"R-Rias?" Zack asked to himself.

Unfortunately, this was not the Rias he thought.

I looked at Zack and asked the obvious question, "You didn't look at this note on the door, did you?"

Zack simply shook his head no, and then said to the Rias lookalike, "Sorry about that-"

All of a sudden, I had a big feeling that the girl inside there is about to scream, so I quickly moved Zack out of the way, and went to the girl as I clamped my hand on her mouth and silenced her with a glare.

"Don't. Even. Try it," I said to her slowly. "Now, I'm only going to say this once. Neither he or I didn't see sign on the door, so we're at fault here. We admitted it. We're sorry for barging in on you like that, but next time, close the door completely."

The girl started to struggle, and I scowled at her and said, "Knock it off!"

It was more of a command than a request.

"I'm going to remove my hand from your mouth now, and we are going to leave. Should you scream, and do anything else I don't like, neither he or I will be held responsible for what misery I'm going to put you through. Do you understand?" I asked the busty redhead, in which she nodded quickly.

"Good. Glad that we could come to an agreement. Now, if you'll excuse me, I got to punish my older brother for his mistake," I said to her as I turned around and walked away, but before I could get to Zack….

"Dayo! Behind you!" Zack warned.

…I quickly responded by ducking from a kick that was aimed at me from behind. Then I quickly the next kick and pushed it away, making the girl stumble back.

"What in blazes are you doing, redhead?!" I growled, as I was seriously not in the mood for any misunderstandings as I have seen it all too often.

"What I'm doing, you say?" the girl asked menacingly as she cracked her knuckles. "That idiot over there saw me using the toilet, and then you came inside, put your hand over my mouth, and told me not to scream! Think about what you just did in the next world!"

Zack replied in his own menacing tone, "Don't say my brother didn't warn you, fake Rias."

That did it for the busty redhead as she went in for another punch, but she's going to feel these punches from mine tomorrow.

BAM!

BONK!

WHAM!

"What's going on here?" Kuki asked as she came to us, along with a young girl with silver-white hair, purple eyes, a modern bust size that's borderline flat (same size as Di), and wearing a black and white goth-like outfit, as they saw my fist steaming with the redhead on the ground holding her head in pain with multiple comedic lumps on it.

"Now listen, Kuki-mom-"

"Kuki?"

It was then that the busty redhead and I looked at each other, wondering why we knew Kuki, with the girl next to Kuki blinking too.

"Oh, boy," Kuki sighed, putting a hand to her head, knowing that this was going be REALLY awkward.

** A few minutes later **

Kotori looked at us at a new table, with Zack and I in a bad mood and were void of any humor at this point, while the busty redhead glared at us in return.

"It was an accident, and nothing more," I said to Kuki.

"Are you making excuses again?" the redhead asked. Zack was narrowing his at her.

In fact, the more he sees her, the more he thinks about that very day when Rias and her friend Akeno was only saying hi to him before going about their own way….

"It's not an excuse; it's the truth," I answered. "You're the one who overreacted, Ms. Angry Sun."

The redhead just bristled in anger.

"Now, now. That's enough," Kuki said in a disciplined motherly tone. "Introduce yourselves, please."

"I'm Mio Naruse," the redhead simply introduced.

Character Stats:

Name: Mio Naruse

Age: 15

Blood: ?

Race: ?

Height: ?

BWH: G-cup

Specialty: Twintail Tsundere Redhead that almost looks like Rias Gremory (In Zack's opinion)

"I'm Maria Naruse, Mio's half-sister! I hope we'll get along after that little mishap," the white-haired girl said with a bright smile.

Character Stats:

Name: Maria Naruse

Age: ?

Blood: ?

Race: ?

Height: ?

BWH: B-cup

Specialty: A little Gothic cutie with a big mouth

"I'm Dayo Kayode. Let's get along, I hope for your sake," I greeted with a shadow of a sincere smile.

"Yant Chichiizumi. We'll have lots of fun together!" Yant greeted with a flirtatious smirk and licked her lips, making Mio shiver and wondering which one of us was worse.

"Vixy Chichiizumi. I hope you like hugs!" Vixy greeted with her breasts bouncing with a huge grin.

"Di Chichiizumi. Nice to meet you!" Di greeted with a wag on her large tail, making Mio having the urge to hug her for her cuteness.

"I'm Zack Itsuka. Let's get along," Zack said with a bit of venom from his voice.

"And I'm his sister, Kotori Itsuka!" Kotori followed before she said to herself, "Those 2 are definitely not normal people. I can also sense some Devil energy in them…."

"And with that, I'll leave it to you guys for you all to know each other when we get home," Kuki commented and smirked at us. "Once again, these 2 guys are the luckiest ones alive. Especially you, Zack. You have 2 new little sisters. That way, both you and Dayo each have 3 cute sisters."

So Zack becomes the big brother of 3 little sisters, and I'm the little brother of 3 big sisters? Great….

"I have a question!" Kotori said as she raised her hand. "What happened to their parents?"

"Their dad's not around. As for Chihaya, she's out of the country, and has asked me to watch them for her, so I'm just returning the favor," Kuki replied.

"Wait a minute… One moment, please," I said as I went to Kuki to another area. "Kuki-ma, if you're watching those 2 for your friend Chihaya, whoever she is, why are they adopted to the Itsuka family?"

"Well, from what I heard from the Chichiizumi Queen Regnant, there are…certain circumstances why, but it's mainly for them to have the benefits of being with us as a family. I know that Chihaya won't be coming back for a long time, and she was worried about them living by themselves," Kuki explained.

After coming to a realization, I asked, "So we are going to be the ones watching them?"

"That's right," Kuki answered. "Not only that, but I'm going back to the States to check on the Itsuka parents, so it'll take a while. That's for sure. I've assured Chihaya that they'll be fine under your watchful eyes. Of course, you have to keep true identity as a Dragon a secret. Other than that, I'm sure there'll be no problem with you all living together. I mean, look at what happened now 5 years prior. First it was just Kotori by herself, then you and Zack, and now us!"

"So you want us all to live as a family as we take care of them," I stated as I folded my arms. "Well, I'm worried about my sisters. They can be….very naughty, at times, especially during the night."

Kuki deviously smiled and giggled in a perverse manner, but quickly disappeared when I looked at her in surprise.

"U-Uh… you didn't see me giggle. Now, keep quiet about this, will ya?" Kuki asked as she pushed me back.

And as we came back, I went to Zack and whispered, "So Kuki-mom wants us to watch over and take care of them while their mom and our mom are away. But we may need to keep an eye on these two just in case something goes wrong. And most of all, we should NOT reveal our true identity and/or powers whatsoever."

"Got it," Zack agreed.

I then looked at Mio and Maria and said, "All right. What do you say? Nothing's wrong about us getting to know each other."

"We understand, and we also want to do that a lot, too," Maria agreed, nodding happily. "Please look after us!"

"Then it's decided!" said Yant with a cheerful smile. "Welcome to our humble family!"

"Then…look after me too, okay?" Mio requested nicely with a smile.

"Of course," Kotori said with a smile before muttering to herself, "Good! They're in! Now I can find out if these 2 are really friend or foe…"

"Just a warning though. If any one of those 2 boys peeks in the toilet again, I'll kill them a hundred times over," Mio growled with a threatening aura.

"Would you like some sugar to go with that foot in your mouth?" I asked ominously with an evil smile with my eyes forcefully closed.

"Two lumps please," Mio grinned back as she cracked her knuckles again.

BAM! BAM!

A few seconds later, Mio was lying on the ground with a bloody face with 2 steaming lumps on her head with her eyes all swirly.

Courteously of me hitting her in the head with a hammer!

Kotori laughed at this. "She got the lumps all right. What an idiot!"

Maria's jaw dropped at this in disbelief.

** One week later **

April 1st, 2023; Itsuka Residence

I was once again being cuddled by my sisters as my head was sandwiched between the bosoms of Yant and Vixy as I've felt an erection coming from all of this. Unfortunately, this is their usual "Wake-Up call".

"What is this?!"

And Zack is about to get a Wake-Up call as well.

(Zack's Room)

(3rd-Person POV)

Zack was once again being roused out of his sleep, but this time, it wasn't from Kotori. This time, he felt something that only guys dreamed of; a blurry sight of yellow clothed-covered fleshy mounds.

"Ah, you're finally awake. Good morning, Zack."

"Good morning, Mio," Zack groaned as he rubbed his eyes to clear them and saw the redhead on top leaning over him. "Just one question: What are you doing in my room?"

"'What', you say? I came in to wake you up in Kotori's favor. I thought boys enjoyed things like this," Mio answered. "Call it a special service on the first day of co-habitation."

"Special service? Usually, it comes with breakfast in bed, but this works too," Zack joked.

"Oh, just get up already," Mio stated seriously with her big breasts bouncing about and her butt grinding on Zack's waist. Of course, while Zack's soul may be gone, he still feels some excitement as his 'shaft' was rising behind her.

"Hey….I think I feel something hard under here," Mio suddenly said, making Zack sweatdrop.

"Um, maybe you never watched what Kuki-mom does at night at work," Zack said dryly as Mio looked at him with a hint of suspicion. "Don't look at me like that. You're the one grinding on me like a stripper in a nightclub."

"That's not it," Mio said as she went under Zack's covers.

"You know you're making matters worse," Zack as he sat up while Mio was rummaging around his covers, with her outline revealing a very compromising position between the two.

"Hey…" Mio said as she got out, holding a box she that was not one of Zack's personal affect, but Mio didn't know that. "What's this?"

"A game?" Zack asked before he frowned and threw off his covers to see several boxes around him.

"What is this?!" he asked loudly, alarming Dayo right next door.

** A few minutes later **

(Dayo's POV)

It was then that I came into the room, expecting Kotori doing her thing again.

"Koko, would you please cut…..it out….?"

I stopped as I saw Zack and Mio on the bed, with boxes of X-rated games all over the place.

"Zack, could you please explain this?" I asked in a growl.

"That's what I'm trying to know!" Zack replied as I looked at one of the boxes, quickly earning several tickmarks on my head as I saw a picture of a girl in an extremely lewd pose with the subtitle of "Plowing my Stepsister's Unclaimed Field ~ecstasy~"

"Are you SERIOUS?!" I asked as I looked at every single box that was a X-rated game, each with "sister" in its subtitles.

Mio shakingly spoke in anger, "No matter where I look, the word "sister"… Y-You're living with us and you have games like that lying around?! I knew it! You intend to make us-"

"VIXY!" I suddenly bellowed, making the house shake, knocking Mio to the floor.

"Yes, my cute Teddy-chan?" Vixy responded after a while, poking her head through the door.

"First of all, none of that Teddy-nonsense. And number 2, quite the funny trick you just did," I said to Vixy, scowling at her who looked confused.

"You know you want to do me soon, Teddy-chan, but I didn't do all of this, so what exactly are you accusing me of?" Vixy questioned.

"THIS!" I pointed at the lewd game and all over Zack's bed.

"As much as I wanted to say that this is a good trick, I didn't do it," Vixy said as she skipped over and around Mio and sat on my lap. I can even vouch Mio here since she looks like she wants to kill Zack a hundred times over."

"Why would I do something like this?!" Mio screeched, shaking one of the boxes angrily with face all red.

"Well, you're in my room, after all," Zack replied in a teasing tone. "Maybe this is all a secret fantasy of yours?"

"It's not!" Mio shrieked, childishly waving her arms.

"Alright, that's enough," Vixy said as she stood up and proceeded to push Mio out of Zack's room before Kotori could come in and see all of this as a misunderstanding. "Also, you're the cause of Zack having a hard-on when you woke him up."

Mio knew exactly of what Vixy meant. "Don't tell me?!"

Vixy quickly shut the door behind her and locked it and placed a barrier inside this room. She then looked a lewd smile on her face.

"So, Teddy-chan, it seems that you have a hard-on too," said Vixy.

Zack and I looked at my hard-on, and she was right. "So I did…."

Vixy leaned back into me as I wrapped my arms around her waist.

"Zack, you may want to watch this, because even if your soul's gone, you can still do this," I said to him. "So consider this as Special Training."

** 30 minutes later **

"Where were you?" Kotori asked, not noticing the 'I just got laid' look on Vixy's face, earning jealous glares from Yant and Di as Zack, Vixy and I all arrived in the Breakfast area in the Dining room.

"I had to help everyone get out of bed, that's all," I lied to Kotori, but she bought it.

Meanwhile…

"Good morning, Dayo, Zack and Vixy!" Maria said brightly.

"Good morning," we all responded in union as I drink some milk (from the Chichiizumi sisters' breasts) in a cup, and some waffles and eggs and sausages while Zack is bringing out some orange juice. All the while, I glared at Maria for some reason.

"Is something wrong?" she asked innocently.

"Your body still needs lots of developing if you're going to pull off that kind out of outfit," I said in a deadpanned tone, as I pointed at her erotic and disturbing choice for an outfit due to her body build. "Especially the naked apron style you're sporting."

"Oh, is that it?" Maria asked slyly before turning around. "Too bad! I'm actually wearing clothes under my apron! And by the way, were you excited? You're a growing teenage boy, after all."

If only you knew, Maria. If only you knew.

"I'll be honest with you, Maria," I said with my arms crossed with a flat tone. "It'll be a cold day in the Devil's lair before I get a hard-on for loli's like you. Even Di tries harder than you. In fact, if you're around C-cup, and then maybe I'll reconsider."

"Aw, how mean!" Maria whined as Zack chuckled, but my eyes are twitching rapidly as I realized something.

"By the way, were you the one that placed all of these lewd games in Zack's bed while he was asleep?" I asked. "Because many of them are involved with sisters and stepsisters."

"That was my housewarming gift! Did you enjoy it?" Maria asked, expectedly with excitement. "I thought he could use it for future reference between me and Mio. The Chichiizumi sisters have given me some great inspiration at that as well!"

I glared at Yant and Di before looking back at Maria and said, "Future reference? More like a big refund. He has no need of these!"

"And besides, why would he need that crap for 'future reference'?" Zack asked in annoyance.

"What else would you do with a step-sister aside from training her to your liking?" Maria asked while making shivering motions.

'What kind of little girl talks like that?!' Zack and I wondered in disbelief and creeped out BIG time at those words.

"Well, if you're not satisfied with a game, then how about real-life?" Maria asked while lifting up her skirt for a tad bit.

"Sorry, but being a pedophile is not my style," Zack dissed Maria as he looked at her up and down, with her chest area….not very appealing. "I happen to enjoy my life as it is, thank you."

** At the Tenguu City streets **

"Why do I have to take a ride with you?" Mio complained as she and I were riding on a red Harley-Davidson Motorcycle in my uncle's honor.

"We're still mapping out and getting used to the area," I answered to Mio, wearing my black helmet to cover my entire face. "Also, do you realize that A. Today is April Fools Day and B. Maria decided to make the most of it by playing a trick on us? Do you even think that we look like the ones who play those stupid lewd games?"

"No, but I know you and Zack are living one! I know that you had sex with your older sister!" Mio countered with her face turning red. "That's not normal!"

"Nor is a 15-year-old with enormous breasts!" I countered back, forcing Mio to hug her chest.

"That's besides the point!" Mio yelled at me, red in the face. Of course, it didn't show as we were both covered in helmets.

"How did you know that even had sex?" I asked her.

Mio decided to change the subject, and I think it's a wise move on her part.

"Well, anyways! I wanted to know what Zack's dream was before I woke him up."

I paused while riding down the street, following the speed limit, of course, before answering, "It was just a memory that took place years ago, and let's just say that it's one of those life-defining moments and never speak of it again."

"Oh…"

Mio decided not press and said, "We're near the supermarket."

After finding, I parked the motorcycle and went inside with Mio. The shopping trip didn't take as we got everything we needed.

"Ah! I need to go and use the restroom. Could you wait for me by the bike, please?" I asked.

"Sure," Mio answered as we went our separate, but only for the moment. And as I headed towards the restroom, Mio was having her own thoughts.

'Dayo is very interesting. And so is Zack. I'll admit that. And I feel bad about what Maria and I are going to do tonight with them and their sisters, but what's this feeling? There's more to them that meets the eye…'

"Hey girl, you lonely? Wanna have a good time?"

Mio's thoughts were interrupted when a gang of delinquents came up to her, with one of them putting his arm around her when he got close as he said his piece, making her disgusted as she threw his arm off of her and stepped back.

"Get your hands off of me! If you touch me again, I'll kill you a hundred times over!" Mio threatened with a fierce glare.

"Oooo, she's gonna kill us guys!" one of them cooed in mock fright before they all laughed at Mio in which the leader got in her face.

"Then let's see you try it."

Mio gritted her teeth and tried to come up with an idea when….

"Hello there, gentlemen. Do you have some business with my step-sister?"

"Dayo…" Mio said in a surprised voice as I came out of nowhere and loaded the groceries in the small bag next to the motorcycles, using magic, of course.

"Dayo? What kind of lame name is that?" the leader sneered towards me.

"Fortunately not as lame as you, numbskull. At least my name stands for joy and happiness. And right now, my step-sister is not showing any of that because of you 4 weasels."

"You little-"

WHAM!

I cut him off hard by placing my foot to his face, sending him flying.

"Great. This town has delinquents desperately trying to rape a woman or two. Well, that's for good for me, because now I have target practice to use while I'm in this area," I said with a sadistic look on my face as the leader's gang surround me on all sides.

"Why you!"

"Let's get him!"

They landed several hits on me, but since that they don't know I'm a dragon and a demigod, their punches means nothing to me as some of their fists were broken in several places. Then I decided to jump up, spin around and land a hard-hitting aerial split-kick to gang's faces, breaking their noses and knocking them to the ground.

"Is that it?" I asked in disappointment. "Then again, you are all nothing but low-lifes here. With that, you lose! Good day, men!" (Famous Reference here! Can you guess what it is?)

I grabbed a startled Mio and placed her in the backseat of the bike, while I went to the front and started it and we soon drove off, leaving the coughing, hacking, and howling-in-pain thugs behind them.

"Well, that was a good way to continue this day," I said before Mio hugged me close, feeling her bosom on my back. "Hm?"

"Sorry," Mio murmured.

"Don't worry about it. I'm no stranger to putting a-holes like them in their place-"

"I'm sorry. Really…"

"…"

I discreetly frowned before hiding it with a smile, and instead frowned on the inside. As if she was apologizing, but not for the situation that has happened.

It was….something else, and I know that it's not a good one.

** Back at the Itsuka Residence; Later that Night **

Kuki-mom is about to leave while Kotori and Di are heading to one of their friends' houses for a sleepover.

"Now then, take care of things, okay?" Kuki asked me asked Zack. "And by the way, expect Di and Kotori to come back within next week."

"Right! Make sure you stay safe and don't take too long!" I said to Kuki as she drove off in her impressive Lexus luxury car. For her to have that from the profits of that restaurant.

Pooters? Really?

** In the Living Room **

(3rd-Person POV)

Mio and Maria were planning on something awful.

"Looks like she's finally gone, and she took two of them with her. No matter. We can handle the other 4. Come, let us begin."

"Mhm… okay."

** At the Entrance **

(Dayo's POV)

So, that leaves me, Zack, Yant and Vixy taking care of Mio and Maria for the following week.

"Well, now that we're alone, Plushy-chan," Yant said as she ran her hands down on her body's curves and gyrated her hips with a sultry smile. "…Vixy and I should slip onto something more…comfortable to serve you. Exclusively."

"And in front of Mio and Maria? Isn't that a bit too early, especially for Maria?" I questioned with an eyebrow.

"I'll keep Maria entertained. Hope's she sensitive…" Vixy said as she grabbed Yant's breasts as squealed.

"She's still developing, so I'm sure she's ticklish, just like us. Now, let's go. Our special outfits are upstairs…" Yant whispered, as the 2 lusty sisters went upstairs.

Zack said to me, "I'm really jealous that you got such sexy sisters."

"Don't remind me," I said to him as we went into the kitchen, taking a detour through the living room, where Mio is sitting on the couch, and Maria's near the window.

"Yo! We're having some good ol' pizza tonight! But if you guys want something different, let us know," I declared before both Zack and I noticed that the room was dark….with something in the air that was prodding with our senses and we didn't like it.

'They are more comfortable in the darkness,' Zack thought. 'Unless….'

"Listen, Dayo. Zack," Mio suddenly said. "I have a request."

I had a bad feeling at what was going to happen next somehow as they are acting like this all of a sudden.

"And….what would that request be?" Zack asked.

Mio answered with an emotionless look on her face, "You two and the rest of your sisters…

"Leave this place."

"…"

We both blinked as I placed a hand on my ear and asked, "Come again? Did you say 'Leave this place'? I don't know if I heard it right…"

At the same time, using the power of telepathy and morse code, I made a series of dots and dashes to Yant and Vixy to get down here and as quick as they can!

Yant and Vixy got the message before they felt a spike of magical energy. And it was not us.

"The crap?!" Zack asked as our eyes' widened at what appeared to be a magic glyph that appeared in front of Maria, who fired a wind spell at us, in which we jumped out of the way, but at the next second, we were both slammed against the ceiling and landed back on the ground, but like a cat after a quick recovery.

'Wind magic. Yet, it was a gravity spell… Impressive,' I thought, already knowing that these 2 are not normal. 'Now then, to investigate even further, I'm going to use-'

"Did you not hear what Mistress Mio commanded?"

My thoughts were cut off as Zack and I looked at Maria who spoke those words menacingly.

"Oh, do we?" Zack asked as we both telepathically spoke to each other to release one of our limiters holding back our power, intending on releasing a 1/8th of it.

"Usually, a human panics when they see Devils like us use magic for the first time in their lives…"

Bingo. These 2 are Devils. And to prove that point, a blue aura surrounded her form, causing the simple black dress to disintegrate as her appearance changed.

"Devils do exist. It's not fantasy or fiction. As well as Angels and Fallen Angels," Maria said, stating the already obvious fact that we know.

Her ears become pointed, her blue eyes glowed, bat wings sprouted from her lower along with a tail, and her outfit became all black and skimpy with her hair ties causing black as well.

"You can't be serious, right?" I asked as I took off my sunglasses, and my right crimson-red eye glowed as I took a good look at the 2 girls, and it tells me who these "sisters" really are.

'One's half-devil, half-human, and the other is half-devil, half-succubus. And Maria's the half-devil, half-succubus one…..unbelievable…..' I mentally sighed in exasperation, now understanding why Maria acts so disturbingly flirty. I HOPE that she doesn't meet Gala at all, as she is a full-fledged succubus, and acts even dirtier….

Anyways, I quickly see Yant and Vixy with Angel Halos on their heads before they disappeared.

"You do realize that you are….you know…young….to be dressed like that," Zack said to Maria before looking at Mio. "Mio, aren't you going to say something?"

"Would you hold your tongue?" Maria asked warningly as her aura intensified. "Being a mere human, you're being very overly disrespectful towards the future Demon Lord as she's the daughter of the original Lucifer."

WAIT A MINUTE!

'Future Demon Lord!? Daughter of the Previous Great Satan!?' Zack, Yant, Vixy and I thought in shock as we all looked at Mio, who was still sitting on the sofa, not looking at any one of us.

Character Stat UPDATE!

Name: Mio Naruse

Age: 15

Blood: AB

Race: Half-Devil, Half-Human

Height: 5' 3"

BWH: G-cup

Specialty: Twintail Tsundere Redhead that almost looks like Rias Gremory (In Zack's opinion), has a somewhat caring side, last descendant of the original Lucifer…..

and Future Great Satan (Lucifer)

** 30 minutes later **

"OK, let's recap," I recalled as I try to gather some info from Maria. "You and Mio are Devils, with Mio being the next possible heir to the title of Great Satan of Lucifer in the Underworld. Is that correct?"

"You're taking this extraordinary well for a human," Maria responded as she explains. "Among the many Supernatural races, the Anti-Supernatural Team, our enemies, and what you would call "heroes", happens to exist as well."

I slightly flinched when Maria mentioned the word "heroes".

"Mistress Mio and I will be using this house as our base of operations in the Human World."

Character Stat UPDATE!

Name: Maria Naruse

Age: Unspecified

Blood: AB

Race: Half-Devil, Half-Succubus

Height: 4' 9"

BWH: B-cup

Specialty: A little gothic cutie with a big mouth… Somewhat of a prankster… and a loli succubus…. Still Illegal!

"If she's a Great Satan candidate, then what about your mom? Chihaya? Kuki-mom's friend?" Zack questioned.

"She's nothing more than a fabrication. We altered her memories. I'm a succubus who can manipulate dreams. I've planted a fake memory of a non-existent female in Kuldelka, who we just happened to cross paths with earlier this morning," Maria revealed as she raised her hands to our faces as we stood up with Zack's hair shadowing his eyes, while my eyes closed behind my sunglasses.

"Now, it's your turn. You two and your sisters couldn't get with us in your house, so it's kinda obvious that things will end bad. Will that work, Mistress Mio?"

"I suppose," Mio responded as she stood up. "That'll do…"

"So… that's how it is?" Zack said, as he's reminded of his tragic past as it seems to be happening all over again. "Really, Mio?"

"I'm sorry, but we need this house your family so graciously provided," Mio said with a blank state. "Relay that to your other sisters as well. Good-bye, brothers. Even if it wasn't long, I had fun."

"No…" I started to say before a bright light from Maria's hands flashed throughout the room for a moment before disappearing.

"OK, Mistress Mio, I've planted a fake memory in them. Now…leave this place immediately," Maria commanded to us. "Your sisters will be next. As I've found out that they're goddesses, it's better safe than sorry. From this point forward, this house is ours…uh?"

To their confusion, we didn't move.

"That's strange. They should've left by now…" Maria noted.

"Maria?" Mio asked with concern.

"No problem. I'll try it again," Maria stated before Zack transformed himself into a Black Cloud, while I disappeared in a burst of pure speed. "Eh? He disappeared?! And he's a cloud?!"

As the thought left her mind, I reappeared behind them near the window as if teleporting, in which I can also do, but I decided to play with these 2 demons, as they caught off-guard.

Meanwhile, Zack is also playing with them as his cloud form is similar to a ghost. He can sense their aura, and even predict what their next move will be.

"When did they…?" Mio asked in shock.

"You dare resist me?!" Maria snarled and prepared a white spell glyph. "You do anything strange like that again, and you'll get hurt!"

Zack then reappeared next to me as I made a "come and get me" motion as icing on the cake, making her even more cross.

"I WARNED YOU!" Maria yelled and launched her attack. I simply said, "Zack, do it."

Zack raised his hand as the bolt went through his hand, causing wind to blow about as he absorbed the attack with his bare hands, neutralizing it with the greatest of ease.

"You absorbed my magic?! That's impossible!" Maria cried out.

"Well, you shouldn't be surprised, little shrimp," I said to her. "In fact, you said it yourself not too long ago. All kinds of Supernatural races exist; from Devils to Fallen Angels, to Angels to Gods and Goddesses…to even Ghosts and Dragons!"

As I said that, Zack transformed himself into his Half-Dragon form, complete with the scales, pointy ears, dragon-like eyes, claws and tail-eve wings; his hair becomes more spikey and all of his features are boned.

As for me, I materialized a unique, mystical but deadly sword called the Moralltach and twirled it around before resting it on my shoulder.

"N-No way!" Mio protested. "The sword that can kill anything in one cut – Moralltach! The Hero Tribe and the Hero Faction are supposed to be with the Khaos Brigade! Why…. are you here?"

She then felt the powerful energy coming from us as I had a bloodthirsty smile on my face.

"What in the world makes you think that I'm part with those hypocritical a-holes?" I asked as I took off my sunglasses, revealing my heterochromia eyes, with my crimson-red eye turning bright red.

"Y-You're a demon?!" Maria screamed as Mio gasped in horror.

"Actually, something even more. Right, Zack?" I asked to Zack.

Zack just growled and roared like a dragon.

"You're Dragons?!" Maria asked in horror.

"That's right, Maria," Zack responded. "And that's not all!"

"Wha-?"

Then out of nowhere, chains sprung up from one of the walls and wrapped themselves around the caught-off guard demons, and lifted them in the air.

"What is this?!" Mio cried out and struggled with Maria.

"I can't get out! And my energy is being sapped!" Maria added in terror as she summoned a spell glyph, but it quickly shatters. "How?!"

"That's the power of our special Goddess chains of love!" Vixy declared as she stepped out of the shadows, wearing a white shirt that barely holds her large chest with her nipples poking out inside her shirt, and a mini-skirt that covers her private parts, while having an Angel Halo on her head as she is in her Goddess form.

"And you made a mistake on trying to infiltrate this place and mess with my cute brother!" Yant added, also stepping out of the shadows, revealing herself wearing only pink flowers that covers her inverted nipples to her now 140cm bust, has long blonde hair, and has fairy and angel wings on her back and has a heart-shaped halo on her head. This is Yant in her Goddess form.

It also appears that Vixy and Yant have used the chains to strain Maria and Mio, respectively.

"Let us go! If you don't, I'll kill all of you a hundred times over!" Mio threatened before Yant pulled the chain harder. "Ack!"

"Now, let's not get carried away, Mio. Trying to threaten to kills us a hundred times over after hypnotizing our mother and attempting to hijack our home is just plain DUMB!" I responded to Mio as she's still to struggle, but to no avail. "Now, Yant, Vixy. Keep these 2 pseudo-sisters in check. I'm making a call with Kuki-mom. And should they try anything funny, let your lewd imaginations run wild. Also, try and get some more info on them."

"Will do," Yant answered as Zack and I went upstairs to make a call so Mio and Maria wouldn't hear anything.

Yant and Vixy each licked their lips as they eyed at Mio and Maria in a perverted manner, making the two demons shiver with fright.

** Upstairs **

Zack and I went back to our normal states as we called Kuki-mom.

[Hey, Dayo! I hope that Mio and Maria are not becoming more than you guys can handle.]

"In more ways than one. You need to come back here ASAP! We have a problem!"

[You mean those 2 being Devils?]

"Yeah, and they tried to take over this house and attempted to—Wait! What did you just say?"

[They struck as soon as I left, despite the protection I helped give them and purposely made it not known. Those idiots…]

"You knew about them?!"

[Of course, I did. I'm half-succubus as well, so Maria's attempt to alter my memories didn't work, but that didn't stop from trying to help them.]

"So, you were pretending to be tricked…"

[Something like that. They've been already marked for investigation, after all.]

"By who?"

[The Khaos Brigade, many of those Devil clans that despise Lucifer… and of course, the AST, the Anti-Supernatural Team.]

"Man… why would they all be observing these 2, especially with the Hero Faction and tribe of the Khaos Brigade and the AST?"

[Well, it's to consider the fact that Mio is the only daughter of the original Lucifer during the 1st Great War.]

"But how is that possible?! The 1st Great War happened over 1,000 years ago."

[True, but don't underestimate the original Lucifer himself. Wilbert von Lucifer was a very strong and peaceful Great Satan at the time as he the other 3 Great Satans of Leviathan, Beelzebub, & Asmodeus all triumphed over many of the warmongering Devil clans, but at the same time, the Fallen Angels and Angels think that these 4 Great Satans are nothing but trouble, as they've heard rumors that Lucifer is also known to be extremely arrogant. So, to save trouble, Wilbert used a spell to teleport the young Mioand some of his servants to the Human World 1,000 years into the future, and he did it just in time as The Great War came to the climax, and those 4 Great Satans all died in the process. Of course, Mio was unaware of any of this. However, what I do know, is that some of those Devil clans that still live today are after Mio to absorb the power she inherited from the original Lucifer. That also includes her Power of Destruction, the two grimoires that her father gave her as a gift, Astil Manuscript and Ilias Fragment, and… the power of the "True Demon Lord", Astral Trinity.]

"Astral Trinity?"

[Yes. You see, Mio has a special magic power called Thema and she obtains the Imperium from the Superbia archive.]

"Wait a minute… Superbia… Isn't that Pride in latin?"

[Yes. Pride. One of the Seven Deadly Sins. Either some of the strongest Devils or human people who can use magic can study Archives. Within each archive are many Thema. There appears to be four Thema per Archive, making 28 in all, and additionally, they are not limited to studying just one of them, but usually picks one as his/her main. Each of these archives are centered around one of the Seven Deadly Sins, they are: Luxuria (Lust), Superbia (Pride), Acedia (Sloth), Ira (Wrath), Avaritia (Greed), Gula (Gluttony), and Invidia (Envy). Most of them would choose an Archive and Thema that is opposite of what their personality is, as it appears to be the easiest for them to use since Magic is irrational by nature.]

"So, in other words, they must think in a way contrary to themselves?"

[Precisely. It is also said that Mio may be holding the strongest Sacred Gear of all time: Apocalypse Bringer.]

"!"

Apocalypse Bringer. Without a doubt, it is indeed THE strongest Sacred Gear of all, even surpassing the Strongest Longinus, the True Longinus. Why? Because that Sacred Gear alone has a part of the soul of my True Sister, 666 (Trihexa), and a part of the soul of The God of the Bible himself.

[I know that you are in shock, right? And that's why Wilbert sealed most Mio's powers before he teleported her out of there. And as for Chihaya, she's the real name of Mio's surrogate mother, who along with her surrogate father, was murdered in front of her by some of the Fallen Angels. Thankfully, she was rescued by those who're still to the original Lucifer after his death, and the current Lucifer now, Sirzechs Lucifer.]

"And to think that Mio had to go through all of this… Just like Zack did, technically…"

[Exactly. So you know what Zack went through, Dayo, so both you and Zack must empathize with her. She's about to become a high school at the new and improved Kuoh Academy, but at the same time, she's suddenly told that she's not only the daughter the original Lucifer, but is destined to become the future Lucifer in the Underworld. Even after Sirzechs and a few of his new friends assigned Maria as her bodyguard, she can't get much help due to the remnants of Wilbert's faction being found and killed by the AST. And with the powers she inherited from her late biological father not fully awakened yet, she's going to be erased sooner or later without help. Even the 4 Great Satans don't have enough room to try and protect her due to their schedules. That's why Pridys and I decided to adopt her and Maria into this family to protect them from the AST and the Khaos Brigade.]

"And you didn't inform us any of this because…"

[It's because for all of you to see them NOT as Devils, but normal people, and bond with them. They need us, and since Sirzechs and his friends helped them out a little bit, I have a feeling that you'll be meeting them soon. Sorry about keeping all of this from you guys.]

"Great, so we're going to reveal ourselves very soon, I suppose."

[That's right. Oh, and also be on the lookout for those Angeloids and Spirits, as well. For some reason, they're also observing Mio, but for different reasons. However, one thing is clear. The time for hiding and playing it safe is over. You 2 are very powerful dragons, and it's high-time to show them how to not mess with you.]

I smiled a bit and said, "So, it looks like things are about to get a little more interesting."

[Indeed. Oh, and beware of Kotori, too. I've heard word about her trying to get you and Zack on a mission that has something to do with sealing a Spirit's power, and the cause of these Spacequakes. However, that's not the main point right now. I've sent you something to keep you 2 motivated.]

And with that, Kuki-mom finally hung up, and a few seconds later, a picture message popped up on my smartphone, revealing a certain picture that was taken yesterday.

(FLASHBACK TIME! – Yesterday)

"Smile, you guys! I'm about to take it!" Kuki-mom called out as we were in front of the Itsuka Residence.

[YES!] they chorused and smiled and for the camera.

"And it looks like a certain stepsister next to me can smile too," Zack said teasingly, pointing at Mio who's right next to him.

"I was thinking that this is kind of nice," Mio admitted sheepishly.

"The first photo of a new family!" Kotori said happily. "I can't wait!"

"Well, don't, because I'm taking it!" Kuki declared as she pressed the button and rushed over to us.

We all smiled at our best, with Mio actually leaning into Zack, who was slightly surprised, and made a peace sign with Maria. Kotori had her hands on Di and Maria's shoulder, and Yant and Vixy both hugged me, blushing madly, with Kuki-mom behind us.

CLICK!

(FLASHBACK END!)

** At the Living Room **

Zack and I were trying to recap about what Kuki said during that earlier phone call. We now learned that despite Mio and Maria being adopted into this family, this was now more of a home-bodyguard, and these 2 devils are the ones that we are going to protect, with one of them being a major target due to the incredible power lying dormant inside her.

And by the way….

SMACK!

Speaking of those 2 Devils, we heard a loud smack, followed by loud pain….and pleasure? Along with the sounds of uncontrollable laughter that got louder and louder.

We soon looked to see what happened. There, on the floor, was a pair of panties, and my sister Yant has a wailing Mio bent over her lap and was now spanking Mio's exposed bottom with her arm that is now glowing. Expectedly, Mio was not enjoying it, but Yant has used her magic to make Mio feel pleasure along with the pain.

As for Vixy, she's using her own angel feathers to tickle Maria, who's now the only one being bound by the chains, as she's now laughing like a hyena, and Vixy decided to use her own magic to make Maria's ticklish areas super-sensitive. Like Mio, Maria was not enjoying it, but had no choice in the matter.

"All right, let them go," I said to Vixy and Yant, in which they released Mio and Maria from their powerful grasp.

As both of them were breathing heavily, Mio said with tears running down her face that was red and filled with embarrassment and anger at the humiliating torture that my sisters gave them, "Why you….I'll make you pay this this!"

"Good luck with that," Yant taunted as she smacked Mio's face with her large breasts.

I've felt a little excited that Yant just….breast-slapped Mio ther—

PANG!

Suddenly, we've felt several hostile presences outside the house.

"It's….warding magic!" Maria breathed out. "It's….the enemy!"

Those words were just enough for me and Zack to rush out the front door, where we found some unwelcome company.

Up high in the sky, the sky itself was swirling purple. That could only mean one of two things: Fallen Angels or Stray Devils.

It proved to be the latter as multiple demonic beings with the appearance of lions and dark in color with a purple hue, all growled viciously, with multiple bat-like wings on their backs.

"Manticores…" I murmured out. "This won't take long."

Zack then went back to his half-dragon state, and began raising his hand as multiple magic circles summoned on all of the monsters below them.

"Now then, it's time for you Stray monsters to make a choice," I said to them. "You either go back to your master and try to make up, or be erased when I snap my fingers."

The manticores roared in response and try to charge forward, but they couldn't. That's because Zack used the Immobilization Spell to let those monsters stay right where they are, courtesy of the circles enveloped below them.

"Well, don't say I didn't warn you, but then again, you're out to try and kill a certain future Lucifer…Not gonna happen!" I finished as I snapped my fingers.

Then suddenly, the circles glowed, making the manticores look down at it. From there, dark beams shot out of the circles, killing each and every one of the manticores instantly.

Mio and Maria stood in awe at the display of our power and skill. Mio was wondering how we're able to take down an entire army of Stray monsters in a short amount of time, while Maria was starting to gain hope as she confirmed her suspicions.

'They're Dragons. Known as the most powerful creatures known in the Supernatural race, they are well-respected and feared. It's best not to anger the Dragons, the rumors say. There's no doubt about it. From their large Dragon wings, that marks the undeniable proof. But after all of the things that we did to them, will they still take us in?'

And as soon as the last manticore has been killed, we went back into the house as I get hugged by Yant and Vixy as a job well done.

"As expected of Plushy-chan," Yant said as my head is hugged between her breasts before releasing me. "However, why were those scary demons here in the first place?"

"Well, to make a long story short," I explained to Yant and Vixy. "Mio is the daughter of the original Lucifer, Wilbert von Lucifer who died in the 1st Great War a thousand years ago, and this girl has inherited his power. Not only that, but there's also rumor that she has THE most powerful Sacred Gear of all time that has the power of the Biblical God and the Apocalypse Beast in there."

Yant and Vixy's jaws dropped in complete disbelief, while Mio and Maria looked shocked that we knew the information as I turned to them and said, "By the way, your power failed to conquer Kuki-mom's mind, but she decided to help you girls out anyway, but left us in charge."

"So, you've been observing us as well… That was out of my expecatations," Maria remarked and groaned into herself.

"Yeah, and despite of what you were trying to pull," Zack responded as he took out my smartphone and showed them the family photo that was taken yesterday. "You're still our family."

"Now, let's not start any melodramatic moments," Vixy said to the 2 step-sisters in which they had tears in their eyes. "We've got to get ready for school next week!"

And as we were all getting ready to go to bed, Zack and I were discussing on not only how to up the security a bit, but also to make sure to prepare for the incoming Spacequakes as well.

However, for some reason, I used my right eye to sense someone balanced on an electric pole with black swept-back spiked hair with a mask with vein designs over his face, pointed ears, and wearing a butler-style suit. And above the man is a Fallen Angel that looks female, thanks to the long red hair that's waving about, and the 6 wings spread behind her back.

They've both disappeared simultaneously. I knew for a fact, that we're going to have some fun later on….

** Somewhere in Synapse, Heaven **

(3rd-Person POV)

Daedalus is looking at Dayo and Zack going inside the house, while the Fallen Angel and the mysterious man are observing them.

She looks down on the floor and said to herself…

"I hope that I made the right choice by sending my daughters down there…. Even if they are Dragons…. They still need to be protected…."

** At an Unknown Location **

"So, with Mio by our side, we've taken one step closer to defect the AST and the Khaos Brigade."

"Yes, but we still need those 2 boys to help us seal the power of the Spirits."

"Don't worry. When April 10th comes, I'll be making my move, since the Spacequakes will soon begin to pick up again."

"Should we tell Lady Rias Gremory about this?"

"Not yet. We'll wait until that time comes."

** At another Unknown Location **

"Yes. I have noticed a change to the observation target's surrounding. She is now in Tenguu City?! With the Spirits and Fallen Angels around that area?!...Understood….I'm heading there now…"

*beep*

'It's fine like this…. Even now, I still can't believe that the village has joined the Khaos Brigade. I can't risk causing trouble by coming into contact with them imprudently. The school semester will begin again soon. And if that wasn't bad enough, the Demon Slayers are also going to join in…..'

** At a Maid Café **

A cute, busty twin-tailed blonde wearing a blue maid uniform suddenly felt something as she looked out the window.

** At a Mansion **

Inside a room reading a book is a young woman with gray hair and violet eyes with a gothic Lolita outfit and just closed the book when she felt a surge of power coming out of nowhere.

"This feeling…" she said to herself.

** In the middle of a forest **

A girl wearing a white yukata is holding a long-sheathed sword as she stood in the middle of a shallow pond.

"So, the hour is finally upon me…." the girl, Himari Noihara, stated.

** In a building **

A girl with long-crimson red hair suddenly woke up as she felt something strange coming out of her chest.

"Zack…" she murmured before she felt the strange feeling going away.


End of Opening Act

To Be Continued….

ED Song: ED Song: Reach For The Stars/Endless Possibility/His World ~2013 Remastered Remix


Next time on Dating with the Supernatural….

Dayo, Zack, and their sisters try to find common ground with Maria in protecting Mio from AST and the Khaos Brigade, as well as any other types of Supernatural races who wants to kill her.

Then on April 10th, Kotori wants Zack and Dayo to come to the diner for lunch, not noticing that there are 2 girls already watching them.

At the beginning of the first day of school for the New Kuoh Academy, Zack finds his old friends again, and 3 new perverts that he uses as Target Practice, while Dayo is assigned as a new teacher in the school.

And later, at the end of the first day, a Spacequake occurs and Zack and Dayo search for Kotori, when they encounter not only a Spirit, but also a Fallen Angel and the AST as well. However, a girl named Himari Nohara, an Ayakashi, protects Dayo and Zack, and claims to protect Dayo at all times.

Meanwhile, Rias Gremory finally meets Zack and apologizes for ignoring him and wants him to be a part of his Peerage, but there are 2 problems. One: She already has 8 new servants which are formerly known as the Trinity 7, and Zack doesn't have a soul anymore.

Finally, Dayo, Zack and their new friends meets the organization of Ratatoskr on their airship, the Fraxinus, where they find out that Kotori, Zack's 14-year-old pseudo-sister, is actually the commander.

A lot of things have happened here, but things are about to pick up on the next Act of "Dating with the Supernatural."


And we are done with the Opening Act! I know that I've already begun another story, but after talking with 2015 Lewamus Prime, I couldn't help but start this one since I am watching "Date A Live", "Highschool DxD", and "Testament of Sister New Devil" all at the same time.

I've already watched Omamori Himari, Sora no Otoshimono, Trinity 7 and seen the H-manga Brandish, so I know what to do about them.

And speaking of "Trinity 7", you may notice that they are a part of Rias' peerage, and why not? Their magic is based off of the 7 Deadly Sins, so that's a no-brainer.

Now, a BIG announcement! Issei Hyoudou WILL be in this story, and as the Red Dragon Emperor! BUT! Issei is a Fallen Angel, and he's actually an Evil Antagonist in this story! MWAHAHAHAHAHAHA!

Kuhdelka Laura Austin is actually an OC from a famous H-manga Japanese writer Matsumoto Katsuya, while Gala is an OC from a famous butt-lover from Argentina Carmessi.

I also got some good inspiration from RekkingPride and SoulEmbrace2010.

Also, I'm going to do something different this time. This time, I'm going to let the people who challenged me, 2015 Lewamus Prime and Glorious Burden, determine the harems for my OC, DK, and Lewamus Prime's OC, Zack Orion.

And I'm also going to post this in both the Highschool DxD fanfiction page and the crossovers page so 2015 Lewamus Prime can see it.

To 2015 Lewamus Prime and Glorious Burden, if you're reading this, look at my PM and tell me what you think of this first episode. Also, if you have any story ideas, you are more than welcome to share it via PM.

To the others, read and review, and no flames! Flames will be ignored!
